2. 1. Insight into coronary artery ectasia

   Author : Usama Boles; Michael Y. Henein; Peter Eriksson; Corrado Tamurino; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Coronary artery ectasia; atherosclerosis; acute coronary syndrome; lipidomic profile; cytokines; prognosis of coronary artery ectasia; kardiologi; Cardiology;

   Abstract : Background:Coronary artery ectasia (CAE) is defined as a diffuse dilatation of the epicardial coronary arteries exceeding 1.5 folds the diameter of the normal adjacent arterial segment and/ or the remaining non-dilated part of the same artery. (1) The incidence of CAE has been variably reported between different nations and ranges between 1. READ MORE

4. 2. The important role of left atrial function parameters in clinical practice

   Author : Ibadete Bytyci; Michael Y. Henein; Roxy Senior; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Left atrial function; Left atrial compliance; left atrial stiffness; Clinical practice; kardiologi; Cardiology;

   Abstract : The aim of this thesis is to evaluate the role of left atrial function in clinical practice based on the following studies:1)    Determining left atrial (LA) structure and myocardial function measurements that predict pulmonary capillary wedge pressure (PCWP).2)    Identifying predictors of exercise capacity in patients with HFpEF and right ventricle (RV) dysfunction.

5. 3. New insights in the assessment of right ventricular function : an echocardiographic study

   Author : Avin Calcutteea; Michael Y Henein; Per Lindqvist; Jan Engvall; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; echocardiography; right ventricle; ischaemic heart disease; pulmonary hypertension; aortic stenosis; aortic valve replacement; three dimensional echocardiography; speckle tracking echocardiography; Cardiology; kardiologi;

   Abstract : Background:  The right ventricle (RV) is multi-compartmental in orientation with a complex structural geometry. However, assessment of this part of the heart has remained an elusive clinical challenge. READ MORE

6. 4. Myocardial electromechanical function in long QT syndrome

   Author : Dafni Charisopoulou; Michael Y. Henein; Annika Rydberg; Anders Jonzon; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long QT syndrome; stress-echocardiography; left ventricular filling; mechanical dispersion; diastolic myocardial function; exercise; arrhythmia; electromechanical window; speckle-tracking echocardiography; myocardial relaxation sequence.; kardiologi; Cardiology; cardiovascular disease; hjärt- och kärlforskning;

   Abstract : AIM: The aim of this thesis is to assess, in LQTS and according to genotype, the myocardial electromechanical (EM) function response to exercise, its relation to symptoms and its response to b-blocker therapy. To achieve this aim, we conducted 4 studies with the following specific objectives: i. READ MORE

7. 5. Survival and functional recovery following valve replacement in patients with severe aortic stenosis

   Author : Wenhong Ding; Michael Y Henein; Eugenio Picano; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aortic stenosis; surgical aortic valve replacement; transcatheter aortic valve implantation; survival; predictor; echocardiography; speckle tracking; ventricular function; twist; strain; Cardiology; kardiologi;

   Abstract : Background: Aortic stenosis (AS) is the most common heart valve disease in Europe and North America. Age-related calcification of the valve is the commonest cause of acquired AS, especially in patients older than 70 years. READ MORE
